The investigators cancer rehabilitation/recovery program, Strong Survivor, has been designed to be delivered digitally, and while there are many such programs currently available on the internet, especially in the time of COVID-19, the novel feature of this program is the delivery of semi-individualized instruction in real time within a small group setting. The program was designed with physician input and by exercise physiologists and a Doctor of Physical Therapy candidate, all with extensive training in both group and individualized exercise for geriatric and cancer survivor populations. Strong Survivor is 16-week iterative curricular program with three core components: aerobic fitness, balance and mobility, and muscular strength and power. Classes will be held twice per week. The first 4 classes will be deployed in a small class of up to 5 people (first 2 weeks), then one class per week with the small class and one class per week is with a larger class of up to 15 people (weeks 3 and 4). The program is then continued for 12 additional weeks in a larger class using principles and exercises specifically trained during the small group classes. All the exercises offered over the course of the intervention are appropriate for the target population and are standardized so all participants receive the same basic instruction, but level of difficulty is scaled to participant experience, capability, and musculoskeletal limitations. Participants will need to have a minimal adequate space and technology to accommodate this instructional method. Specifically, they will require an internet connected device with a camera that is at least 7 inches square. (tablet size or larger). Additionally, participants' will need to have adequate space to both set up a computer/camera and move around. The minimal acceptable space for this is 6+ feet with an unobstructed view (from a table for instance) of a 2 x 2 open space. All study participants will complete a clinic visit before they join the classes and after the last class to evaluate cardiorespiratory fitness, strength, balance and posture and answer questionnaires about quality of life and system usability.
